R65C21P4E

The R65C21P4E peripheral interface adapter (PIA) is designed to solve a broad range of peripheral control problems in the implementation of microcomputer systems.

Features of the R65C21P4E are:(1)low power CMOS N-well silicon gate technology;(2)direct replacement for NMOS R65C21P4E PIA;(3)two 8-bit bidirectional I/O ports with individual data direction control;(4)automatic "handshake" control of data transfers;(5)two interrupt with program control;(6)1,2,3 and 4 MHz versions;(7)commercial and industrial temperature range versions;(8)wide variety of packages;(9)single +5Vdc power requirement;(10)compatible with the R65C21P4E of microprocessors.

The absolute maximum ratings of the R65C21P4E can be summarized as:(1):the parameter is supply voltage,the symbol is VCC,the rating is -0.3 to +7.0,the unit is V;(2):the parameter is input voltage,the symbol is VIN,the rating is -0.3 to VCC+0.3,the unit is V;(3):the parameter is output voltage,the symbol is VOUT,the rating is -0.3 to VCC+0.3,the unit is V;(4):the parameter is operating temperature range commercial,the symbol is TA,the rating is 0 to +70,the unit is ;(5):the parameter is operating temperature range industrial,the symbol is TA,the rating is -40 to +85,the unit is ;(6):the parameter is storage temperature,the symbol is Tstg,the rating is -55 to +150,the unit is .
